The solution is x = -61/8 and y = -1/2.
<u>Step-by-step explanation</u>:
The given equations are -4x + 3y = 29 and 2y + 5 = 4
<u>Step 1</u> : There is no x term in the second equation.
<u>Step 2</u> : Solve for y, 2y = 4 -5
y = -1/2
<u>Step 3</u> : Substitute y = -1/2 in first equation and solve for x.
<u>Step 4</u> : -4x + 3(-1/2) = 29
-4x -(3/2) = 29
-8x -3 = 29
2
-8x = 58 + 3
x = -61/8

Step-by-step explanation:
X^2+10x+16＝0
First, you find factors of 16.
1 x 16
2 x 8
4 x 4
Next, you find which of the factor pairs adds up to 10 (from the 10x). In this case, 2 x 8 because 2 times 8 is 16 and 2 plus 8 is 10.
Then, the equation will be written out as: (x+2) (x+8). Take those two equations and set them equal to 0, and then solve.
x+2＝0
-2 -2
x＝-2
x+8＝0
-8 -8
x＝-8
So, your answers are x＝-2 and x＝-8. You can check by plugging in those two numbers as x.
