4(x + 6)
4 × x = 4x
4 × 6 = 24
3(3x + 4)
3 × 3x = 9x
3 × 4 = 12
9x + 4x = 13x
12 + 24 = 36
So your answer is B) 13x + 36. I hope this helps!
Answer:
x= 5/4 ; y= -7/4
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
3x+y=2;5x−y=8
Step: Solve3x+y=2for y:
3x+y+−3x=2+−3x(Add -3x to both sides)
y=−3x+2
Step: Substitute−3x+2foryin5x−y=8:
5x−y=8
5x−(−3x+2)=8
8x−2=8(Simplify both sides of the equation)
8x−2+2=8+2(Add 2 to both sides)
8x=10
8x
