The answer is x=-2

8(-2x+1=30-(-4+3x)
Distribute 8 through the parentheses
-16x+8=30-(-4+3x)
Add the number
-16x+8=34-3x
Move the variable to the left-hand side and change its sign
-16x+8+3x=34
Collect like terms
-13x=34-8
Divide both sides of the equation by -13
-13x/-13=26/-13

X=-2

Answer:

-2

Step-by-step explanation:

8 (-2x + 1) = 30 - (-4 + 3x) Distribute

-16x + 8 = 30 + 4 - 3x Combine like terms

-16x + 8 = 34 - 3x Rearrange terms

-13x = 26 Divide by -13 on both sides

x = -2

Answer:

$2(2x+7)$

Step-by-step explanation:

we have

$4x+14$

we know that

$4=2^2=(2)(2)\\14=(2)(7)$

substitute

$(2)(2)x+(2)(7)$

Factor 2

$2[(2)x+(7)]$

Solve the system of equations. x+y=4 y=x^2 - 8x + 16 a) {(-3,7).(-4, 8)} b) [(4,0)} c) {(3,1),(4,0) d) {(3,7). (4.0)} e) none

Answer: The required solution of the given system is

(x, y) = (3, 1) and (4, 0).

Step-by-step explanation: We are given to solve the following system of equations :

$x+y=4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\y=x^2-8x+16~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)$

From equation (i), we have

$x+y=4\\\\\Rightarrow y=4-x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)$

Substituting the value of y from equation (iii) in equation (ii), we get

$y=x^2-8x+16\\\\\Rightarrow 4-x=x^2-8x+16\\\\\Rightarrow x^2-8x+16-4+x=0\\\\\Rightarrow x^2-7x+12=0\\\\\Rightarrow x^2-4x-3x+12=0\\\\\Rightarrow x(x-4)-3(x-4)=0\\\\\Rightarrow (x-3)(x-4)=0\\\\\Rightarrow x-3=0,~~~~~~~x-4=0\\\\\Rightarrow x=3,~4.$
