Answer:
See below.
Step-by-step explanation:
1*(-7+4) = 1*-7 + 1*4 = -7 + 4 = 3
Answer:
-3
Step-by-step explanation:
- Plug in the value of x: 2(-3) + 3
- 2(-3) = 2 × -3 = -6
- Plug -6 in: -6 + 3
- -6 + 3 = -3
I hope this helps!

Answer:
15x - 4y =-50 -----(i)
3x - 2y=-16 --------(ii)
Using Substitution
From (i)
15x=4y-50
x=4y-50/15
Substitute x=4y-50/[15] into eqn (ii)
3x - 2y= -16
3[4y-50]/15 - 2y =-16
Multiply through by 15 to clear the fraction
3(4y - 50) - 30y=-240
12y - 150 -30y=-240
12y-30y=-240+150
-18y = -90
y=90/18
y=5.
Substitute into any eqn of choice to get x
3x - 2y=-16
3x - 2(5)=-16
3x - 10=-16
3x=-16+10
3x=-6
x=-6/3
x=-2.
x= -2
y=5
