The answer is SR=3
2x+23+x+21=14
Solve for x you get
x=-10
Substitute x
2(-10)+23=3
Answer:
yes
Step-by-step explanation:
because both of them are horizontal straight lines

because you add all the number making sure it's not greater than 60 and carry over to the next hour if it is
Answer:
(3,-2)
Step-by-step explanation:
Given equations of line
3x-2y=13
2y+x+1=0
=> x = -1 -2y
Point of intersection will coordinates where both equation have same value of (x,y)
top get that we have to solve the both equations by using method of substitution of simultaneous equation.
using this value of x in 3x-2y=13, we have
3(-1-2y) -2y = 13
=> -3 -6y-2y = 13
=> -8y = 13+3 = 16
=> y = 16/-8 = -2
x = -1 - 2y = -1 -2(-2) = -1+4= 3
Thus, point of intersection of line is (3,-2)
