Multiply the bracket by 5
10x+25= 4x-7
10x-4x+25= 4x-4x-7
6x+25= -7
6x+25-25= -7-25
6x= -32
Divide by 6 for 6x and -32
6x/6= -32/6
x= -32/6
divide by 2 for -32/6
x= -16/3
Answer is -16/3 ( improper fraction) or -5 1/3 ( mixed number)
Answer:
c)124
Step-by-step explanation:
3*2+7*8+12*4=124
We can put the two equations together with substitution, and we get
3x + 2y = 30
Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.
