Question

If 1.2x +0.04=2x-3.56 then,what is the value of x​

Answer 1

Answer:

The equations are

⇒.04x+.02y=5....eq(1)

⇒x=

.04

5−.02y

⇒.5x−.4y=30....eq(2)

Substitute the value of x in eq (2)

⇒

.04

.5(5−.02y)

−.4y=30

⇒2.5−.01y−.016y=1.2⇒−.026y=−1.3⇒y=50

Substitute the value of y in eq (2)

⇒.5x−.4(50)=30⇒.5x=50⇒x=100

⇒x=100,y=50

Answer 2

Answer:

4.4

Step-by-step explanation:

2x-1.2x=3.56-0.04

0.8x=3.52

X=3.52/0.8

=352/80

=4.4
