Answer:
I believe it would be C
Step-by-step explanation:
1st one on second row I think
4y = -23 + 39
4y = 16
y = 4
Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9
x = -9
y = 4
The given expression is : (4x – 7.2) + (-5.3x-8)
Simplify :
Open the brackets :
(4x – 7.2) + (-5.3x-8) = 4x - 7.2 - 5.3x - 8
Arrange the variable and constant terms together :
(4x – 7.2) + (-5.3x-8) = 4x - 5.3x - 8 - 7.2
Solve the variable and constant terms together :
(4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
Since, the variable and constant term can not solve together so the above equation is the simplest form:
(4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
Answer : (4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
