Answer:

None of those

Step-by-step explanation:

a) -1xy + 74 \neq -2y + 32 x + 74\\\\ b) 32x - 2(y + 72) = 32x -2y -144\\32x -2y -144 \neq -2y + 32 x + 74\\ \\ c) -14y + 32(y +x) = -14y + 32y+32x \\ -14y + 32y+32x\neq-2y + 32 x + 74\\ \\d) -2y + 12 (3x + 72)  = -2y + 36x+864\\-2y + 36x+864\neq -2y + 32 x + 74\\ \\e) 14(-8y + 6x + 7) = -112y +84x+98\\  -112y +84x+98 \neq -2y + 32 x + 74

2x+4y=0

substitute y with 0

2x+4(0)=0

solve the equation

2x+0=0

2x=0

divide by 2 on both sides

x=0

4x+8y=7

substitute y with 0

4x+8(0)=7

solve the equation

4x+0=7

4x=7

divide by 4 on both sides

x=7/4 or x=1 3/4 or x=1.75

3x-7y=-29

2x+2y=6

solve the bottom equation

3x-7y=-29

x=3-y

substitute for x

3(3-y)-7y=-29

solve the equation

y=19/5

now substitute for y

x=3-\frac{19}{5}

solve for x

x=-4/5

the possible solution of the system is the ordered pair

(x,y)=(-\frac{4}{5} ,\frac{19}{5})

mel-nik [20]

Answer:

x=7.78

Step-by-step explanation:

142=10x+8x+2

Move all numbers with the same variables to each side to separate them.

142-2=10x+8x

140=18x

Divide by 18.

x= 140/18

x=7.78
