Can someone pls explain to me Grade 7 algebra could u simplify these: 2.4u + 1.4 = 23, 2x = 50, e-10=80
2.4u + 1.4 = 23 subtract 1.4 from both sides
2.4u = 21.6 divide both sides by 2.4
u = 21.6 / 2.4 = 9
2x = 50 divide both sides by 2
x = 25
e-10=80 add 10 to both sides
e = 90
And another example: 2w-1=11
+14
