We are to solve this for x:   <span>1.8-3.7x=-4.2x+0.3

Combine like terms.  First, add 4.2x to both sides.  This results in 1.8+0.5x = 0.3, and then 0.5x = 0.3-1.8.

Next, 0.05x = -1.5, or 5x = -150, and x = -30. 

Must check this result by substitution of -30 for x in the original equation.

Is  </span><span>1.8-3.7(-30)=-4.2(-30)+0.3 true or false?</span>

The answer is 3

Step-by-step explanation:

add -4.2 to -3.7 to get 0.5, then subtract 1.8 by 0.3 to get 1.5 on the other side. then you divide 1.5 by 0.5 to get 3. Hope this helps and have a good day!:)

Solve the equation by elimination
SVEN [57.7K]

Answer:

(1,-7)

Step-by-step explanation:

y= -9x + 2.............equn(1)

y= -3x - 4..........................(2)

subtract equation (1) from equn. (2)

0= -6x + 6

subtract 6 from both sides

0-6= -6x + 6-6

-6 = -6x

divide via by -6

-6/-6 = -6x/-6

x=1

to solve for y, put x in any equation

equation (1)

y=-9x+2

y=-9(1)+2

y=-9+2

y= -7
