Answer:

x = 6

Step-by-step explanation:

Givens

There are 3 sides. All are equal to (4x - 3)

Their sum = 63

Formula

3(4x - 3) = 63

Solution

3(4x - 3) = 63 Divide by 3
12x - 9 = 63 Add 9 to both sides
12x = 63 + 9
12x = 72 Divide by 12
x = 72/12

x = 6 Answer

Fittoniya [83]

Answer:

-2

Step-by-step explanation:

8 (-2x + 1) = 30 - (-4 + 3x) Distribute

-16x + 8 = 30 + 4 - 3x Combine like terms

-16x + 8 = 34 - 3x Rearrange terms

-13x = 26 Divide by -13 on both sides

x = -2
