Simplifying
7x + -10x + 18 + 2x = -5
Reorder the terms:
18 + 7x + -10x + 2x = -5
Combine like terms: 7x + -10x = -3x
18 + -3x + 2x = -5
Combine like terms: -3x + 2x = -1x
18 + -1x = -5
Solving
18 + -1x = -5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-18' to each side of the equation.
18 + -18 + -1x = -5 + -18
Combine like terms: 18 + -18 = 0
0 + -1x = -5 + -18
-1x = -5 + -18
Combine like terms: -5 + -18 = -23
-1x = -23
Divide each side by '-1'.
x = 23
Simplifying
x = 23
Let the length of the shortest side = x
The two longer sides that are equal = 3x
The are two equal longer sides, so their total is 3x + 3x = 6x
3x+ 3x + x= 35 Collect like terms on the left
7x = 35 Divide by 7 on both sides
x = 35/7
x = 5
Answer
Two long sides -- 15 cm each
Shortest side -- 5 cm
