(Hope this helps can I pls have brainlist (crown)☺️)
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x To find the y-intercept, substitute in 0 for x and solve for y.
Slope: 
x-intercept(s): ( 5 , 0 )
y-intercept(s): ( 0 , 4 )
6/10 = 3/5
Simply divide the numerator and denominator of 6/10 by 2. 6/10 is the same as 3/5.
0.7(5x+15)=2.9 -(x+3)
3.5x+10.5=2.9-x-3
3.5x+10.5= -0.1- x
4.5x= -10.6
x= -2.3555...
Check:
0.7(5(-2.3555...) +15) = 2.9 -(x+3)
2.2555... = 2.2555...
Answer:
x=2
Hope this helps!
