5(8x-2)=270
distribute the 5 into 8x-2
5*8x-5*2=270
you get
40x-10=270
combine like terms
40x=280
divide both sides by 40 to find x
x=7

Answer:
18
Step-by-step explanation:
Solve the separate part of the equation first
6(4) 6(-2) would equal 24-12
Add it back in to get: 10 - 4 + 24 - 12
-4-12 and 10+24 are the like terms so
10+24 = 34 and -4-12 = -16
Equation in the end: 34-16
Simplify that to: 34-16 = 18
Answer:
x=6 y=7
(6,7)
Step-by-step explanation:
y=x+1 5x+3y=51
to solve this you can use the substitution method or anotherone i forgot the name of. so in with that being said, the substitution method is the wa to go.
start with the first equasion
5x+3y=51
substitute
5x+3(x+1)=51
distribute
5x+3x+3=51
add like terms
8x+3=51
solve equasion
8x=48
x=6
now onto the next equasion
y=x+1
substitute
y=6+1
add like terms
y=7
