Let's solve your equation step-by-step.

5=(−4)(8)+b

Step 1: Simplify both sides of the equation.

5=(−4)(8)+b

5=−32+b

5=b−32

Step 2: Flip the equation.

b−32=5

Step 3: Add 32 to both sides.

b−32+32=5+32

b=37

Solve the equation <br> (If possible please show work)

deff fn [24]

Answer:

$x=-3$

Step-by-step explanation:

So we have the equation:

$-2(-x-4)+3=-7-4x$

First, distribute the left side:

$-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x$

Add values on the left side:

$2x+11=-7-4x$

Add 7 to both sides. The right side cancels:

$(2x+11)+7=(-7-4x)+7\\2x+18=-4x$

Subtract 2x from both sides. The left side cancels:

$(2x+18)-2x=(-4x)-2x\\18=-6x$

Divide both sides by -6:

$(-6x)/-6=18/-6\\x=-3$

Therefore, x equals -3.

Find the missing number so that the equation has infinitely many solutions.

Alex17521 [72]

equation has infinitely many solutions has the same number on both sides of the equal sign

-3x -21 + x + 5 = -20x -16

-2x -16 = -20x -16

so either you have -18x on the left or +18x in the right
