X/8-4=7 X/8=11 X=11 x 8 X=88 ;-)
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
3x+7=19 3x=12 minus 7 from both sides x=4 divide by three on both sides leaving just what x equals
(-3) - (-7) = (-3) + (+7) = (-3) + 7 = 4
Divide 28 by 4. X = 7
Question 3C: Four minus seven equals negative two.
It is a linear equation in a single variable, w.
-7
it is minus 4 (-4) the right answer
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
6 - 5 + 7 * 4 - 3
3x+7=19 3x=12 minus 7 from both sides x=4 divide by three on both sides leaving just what x equals
21
1*-7 +7-4=-4
3
7 − 43/4 = 21/4
7-3=4
No it is -7 but -3- -4 = 1
