Answer:
x=4 y=7
Step-by-step explanation:
When multiplying 3x by -2, you get -6x. -6x and 6x cross out. You're left with -2y=-2 and -2y=10.
Since we have the 2.1 next to the parenthesis, we need to first distribute.
2.1 * x & 2.1 * 5
2.1x + 10.5
Then we take that and add the equals seven to the problem to move onto the next step.
2.1x + 10.5 = 7
We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.
2.1x + 10.5 = 7
- 10.5 -10.5
2.1x = -3.5
To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.
2.1x = -3.5
/2.1 /2.1
x = 1.66666666667

Answer:
B:
Step-by-step explanation:
brainliest pls
The next step would be:
-0.4 -0.4
explanation:
You would need to move the variables to one side so minus the 0.4 would move the numerical number to the other side which leave the variable to the other side.
Hope this makes sense :)
