Answer:
x = -9
Step-by-step explanation:
2x + 8( x + 3 ) = 3( x - 13 )
Dstribute;
2x + 8 ( x + 3 ) = 3 ( x - 13 )
2x + ((8)(x)) + ((8)(3)) = ((3)(x)) - ((13)(3))
2x + 8x + 24 = 3x - 39
Combine like terms;
2x + 8x + 24 = 3x - 39
10x + 24 = 3x - 39
Inverse operations;
10x + 24 = 3x - 39
-3x -3x
7x + 24 = -39
-24 -24
7x = - 63
/7 /7
x = -9
first distribute 8 and 3 through parenthesis. this makes the equation
2x+8x+24=3x-39
collect like terms, such as “2x+8x” this becomes 10x. plug in 10x.
10x+24=3x-39. now move variable and constant. 10x-3x=-39-24
collect like terms again. 10x-3x becomes 7x.
7x=-39-24.
-39-24=-63
7x=-63 divide both sides by 7.
x=-9
