Answer:
x=12
Step-by-step explanation:
(3x-2)/4+5(x+3)/2
3x-2+20=2(x+3)
3x+18=2x+6
3x-2x=6-18
=x=-12
Answer:
x = -12 not 12 as in previous response
Step-by-step explanation:
(3x-2)/4 + 5 = (x+3)/2 put terms on left and constants on right
(3x-2)/4 - (x+3)/2 = -5
multiply all terms by 4
(3x-2) - 2(x+3) = -20 now simplify by distributing -2 in second term
3x - 2 - 2x - 6 = -20 combine like terms
x -8 = -20 now add 8 to both sides
x = -12

Answer:
x=3, y=-2. (3, -2).
Step-by-step explanation:
4x+2y=8
5x+3y=9
---------------
simplify 4x+2y=8 into 2x+y=4
-----------------
2x+y=4
5x+3y=9
----------------
y=4-2x
5x+3(4-2x)=9
5x+12-6x=9
-x=9-12
-x=-3
x=3
2(3)+y=4
6+y=4
y=4-6
y=-2
1. D
Y=x+4.
That’s the answer
