Which task you exactly need help with ?
Answer:
4x
Step-by-step explanation:
Y = 5 - 3x....so sub in 5 - 3x for y in the other equation
5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1
now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2
check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)
so ur solution is (1,2)
Answer:
It would make it 3x
Step-by-step explanation:
4x is just a simplified version of 4 multiplied by x
4*x-x wouldn't equal 4 because you aren't following
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
(PEMDAS)
Fist if there is 4 sides on the base you would divide 216/4 =54
Or if there are 2 sides you would divide 216/2= 108
