Troyanec [42]
Take the coefficient of the x-term, half it, then square that. add this to both sides

x² + 16x. coefficient of x is 16. half of 16 is 8. 8²=64

x² + 16x + 64 =64. this is your answer but to continue

x² + 16x + 64 = 64
(x+8)² = 64
x+8 = ✓64

Which expression can be substituted for y in the top equation of the
maria [59]

Answer:

Y=7+3x, x=-3, y=-2

Step-by-step explanation:

3x-5y=1. Equation 1

3x-y=-7. Equation 2

-y=-7-3x isolate for y in equation 2

y=7+3x multiplied by -1 to get positive y

3x-5(7+3x)=1 substitute y value of equation 2 (7+3x) into equation 1

3x-35-15x=1

-12x=36

x=-3

solve for y.

3x-5y=1

3(-3)-5y=1

-9-5y=1

-5y=10

y=-2

1. 1.4(x−1.6)=1.6(x−1.4)<br><br>solve<br>2. 1.4(x−1.6)=1.6(1.4−x)<br><br>solve
Bezzdna [24]
1.
1.4( x - 1.6) = 1.6(x - 1.4) \\ 1.4x - 2 .24 = 1.6x - 2.24 \\ 0.2x = 0 \\ x =  0
2.
1.4( x - 1.6) = 1.6(1.4 - x) \\ 1.4x - 2 .24 = 2.24 - 1.6x \\ 3x = 4.48 \\ x =  1.4933333
