One-Step Equations - ISEE Lower Level: Quantitative Reasoning

$x = 0.7$. Subtract 0.4 from both sides to isolate $x$ in the decimal equation.

$x = 2.8$. Add 2.5 to both sides to solve for $x$ with decimals.

$x = -12$. Multiply both sides by -1 to isolate $x$ and reverse the sign.

$x = \frac{7}{2}$. Multiply both sides by 5 to isolate $x$ and obtain the fraction.

$x = \frac{1}{2}$. Subtract $\frac{1}{3}$ from both sides to isolate $x$ in the equation.

$x = \frac{7}{8}$. Add $\frac{3}{4}$ to both sides to solve for $x$ with fractions.

$x = 10$. Add 8 to both sides to isolate $x$, as adding the opposite of -8 balances the equation.

$x = -6$. Subtract 5 from both sides to isolate $x$, since subtracting a negative is adding.

$x = 18$. Multiply both sides by 2 to solve for $x$ in the division equation.

$x = -18$. Multiply both sides by 2 to isolate $x$ and handle the negative value.

$x = 18$. Divide both sides by 0.5, equivalent to multiplying by 2, to solve for $x$.

$x = -24$. Multiply both sides by -3 to find the value of $x$.

$x = 13$. Subtract 7 from both sides to isolate $x$ while keeping the equation balanced.

$x = 13$. Add 9 to both sides to isolate $x$ and maintain the equation's equality.

$x = -9$. Subtract 15 from both sides to solve for $x$ in the equation.

$x = 9$. Add 12 to both sides to isolate $x$ and preserve balance.

$x = 7$. Divide both sides by 5 to find the value of $x$.

$x = -7$. Divide both sides by -4 to solve for $x$ in the equation.

$x = 30$. Multiply both sides by 6 to isolate $x$ and maintain equality.

$x = -6$. Multiply both sides by 4 to solve for $x$ in the fractional equation.
