Enter the value of x that makes the given equation true.

3(5 - x) = 7x - 2

exact form: x=17/10

Decimal form: x=1.7

mixed number form: 1 7/10

x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)

Step-by-step explanation:

3(5-x) = 7x - 2

3 * 5 - 3* x = 7x - 2 (brackets means multiply)

15 - 3x = 7x - 2 (when over equal sign negative changed to positive)

15 + 2 = 7x + 3x

17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)

17/10 = x
