Step-by-step explanation:
1- 2+5=7
7=7
proof y=7-2
y=5#
2- 2*4-3=5
5=5
proof 2a=5+3
a=8/2
a=4#
3- 10-4=6
6=6
proof -q=6-10
-q=-4
q=4#
4- 2*4-5=3
3=3
proof 2t=3+5
t=8/2
t=4#
5- 14=27-13
14=14
proof X=27-14
X=13#
6- 5x+20=35
5*3+20=35
35=35
proof 5x=35-20
x=15/5
x=3#
7- -3*(-5)=15
15=15
proof X=15/(-3)
x=-5#
8- 5*(-1)-3=3*(-1)-5
-8=-8
proof 5x-3x=-5+3
2x=-2
x=-2/2
x=-1#
9- 3*4+4=5*4-4
16=16
proof 3y-5y=-4-4
-2y=-8
y=8/2
y=4#
10- 3x-9=10x+5
3*(-2)-9=10*(-2)+5
-15=-15
proof 3x-10x=5+9
-7x=14
x=14/(-7)
x=-2#
