(4-5x)+43=3-32(-82)<br> please answer!!

kotykmax [81]

Answer:

x = -516

Step-by-step explanation:

(4 - 5x) + 43 = 3 - 32(-82) {Multiply 32 and (-82)}

4 - 5x + 43 = 3 - (-2624)

4 - 5x + 43 = 3 + 2624 {add 4 and 43 in LHS}

-5x + 47 = 2627 {Subtract 47 from both sides}

-5x = 2627 - 47

-5x = 2580 {Divide both sides by (-5)}

x = 2580/(-5)

x = -516

-1/2 +2=-x+7 how do you figure this out

Feliz [49]

Answer:

x = 5.5

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

$-\frac{1}{2} +2=-x+7$

$-\frac{1}{2} +2= 1.5$

$1.5=-x+7$

-7 -7

$-5.5 = -x$

Divide both sides by -1.

$5.5 = x$
