Question

solve this answer if you can​

Answer 1

1)

-5x+4=-4x-3

-5x+4x= -3-4

-x= -7

x= 7

2)

1.8= y/2.5

y= 1.8*2.5

y= 4.5

3)

2t/5= 20

t= 20*5/2

t= 10*5

t= 50

4)

100x+5x+5=20x+10

105x-20x=10-5

85x= 5

x= 5/85

x=1/17

Answer 2

Answer:

1) -5x+4=-4x-3

4+3=5x-4x

7=1x

x=7

2)1.8=y÷2.5

1.8×2.5=y

4.5=y

y=4.5

3)2t÷5=20

2t=20×5

2t=100

t=100÷2

t=50

4)100x+5x+5=20x+10

105x-20x=10-5

85x=5

x=5÷85

x=1/17
