Answer:
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
