7x + 3(5 - 3x) =5 i keep seeing answers on here claiming to be step by step but i end up confused. what is x equal to?

X = 5

Step-by-step explanation:

First expand, 7x + 15 - 9x = 5

Simplify, -2x + 15 = 5

Additive property of Addition/Subtraction , (-2x + 15) - 15 = (5) -15

Simplify, -2x = -10

Divide by -2, (-2x)/-2 = (-10)/-2

Simplify, x = 5

Substitution for checking your answer, 7(5) + 3(5-3(5)) = 5

35 + (15-45), simplify, 35 - 30 = 5

Thus the final answer can be concluded as X = 5

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
