Answer:
8.333333
Step-by-step explanation:
3x+2(4+6x)=133
3x+8+12x=133 First I distibuted the 2 too the 4 and 6x
15x+8=133 Then I added the x es 3x and 12x
15x+8-8=133-8 Then I subracted 8 from both sides
15x=125 That leaves with this
15x/15=125/15 Now I divide 15 from both sides to isolate x
x= 8.33333 that is the answer
check
3x+2(4+6x)=133
3*8.333333+2(4+6*8.333333)=133
24.999999 +2(4+ 49.999998)=133
24.999999+2( 53.999998)=133
24.999999+107.999996=133
132.999995=133
