First subtract 3 to both sides to isolate x
2-21-3 = -x
Now calculate what is 2-21-3.
-19-3 = -x
-22 = -x
Now divide both sides to -1 to get x positive.
-22 / -1 = -x / -1
22 = x
So x is equal to 22.
If it is right brainiest please.
<span>Multiple: 9 * <span>8/9</span> = (<span>9*8/1*9) </span>= <span>72/9</span> = 8/1 = 8
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator <span>GCD(72, 9) = 9</span></span>
-10b--3b= 7b and then 113-71=42 and 42 divide it by 7b which is gonna be b=6
