Solve 3(5z-7)-2(9z-11)=4(8z-13)-17

Question

Solve the equation

z = 2

Evaluate

3 (5 z - 7) - 2 (9 z - 11) = 4 (8 z - 13) - 17

Move the expression to the left side

3 (5 z - 7) - 2 (9 z - 11) - (4 (8 z - 13) - 17) = 0

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

3 (5 z - 7) - 2 (9 z - 11) - 4 (8 z - 13) + 17 = 0

Calculate the sum or difference

More Steps

- 35 z + 70 = 0

Move the constant to the right-hand side and change its sign

- 35 z = 0 - 70

Removing 0 doesn't change the value,so remove it from the expression

- 35 z = - 70

Change the signs on both sides of the equation

35 z = 70

Divide both sides

\frac{35 z}{35} = \frac{70}{35}

Divide the numbers

z = \frac{70}{35}
