0.4(y-0.2)+1.5=0.7y-0.38解方程
0.4(y-0.2)+1.5=0.7y-0.38
解方程
0.4(y-0.2)+1.5=0.7y-0.38解方程
0.4(y-0.2)+1.5=0.7y-0.38
0.4y-0.08+1.5=0.7y-0.38
0.7y-0.4y=1.5+0.38-0.08
0.3y=1.8
y=1.8/0.3
y=6
0.4(y-0.2)+1.5=0.7y-0.38
0.4y-0.08+1.5=0.7y-0.38
0.7y-0.4y=1.5-0.08+0.38
0.3y=1.8
y=6
0.4y-0.8+1.5=0.7y-0.38;
1.08=0.3y
y=3.6
解方程 0.4(y-0.2)+1.5=0.7y-0.38
0.4(y-0.2)+1.5=0.7y-0.38
0.4(y-0.2)+1.5=0.7y-0.38解方程
0.4(y-0.2)+1.5=0.7y-0.38
-0.7y+0.2=-0.3y+0.1 y=?
(y-0.3)/0.2=(0.7y+0.5)/0.5-1.5
-0.7y+0.2= -0.3y+0.1
0.2y²-0.4y=0.1
计算 (y-0.3)/2=(0.7y+0.5)/0.5-1.5应该是(y-0.3)/0.2=(0.7y+0.5)/0.5-1.5
··0.4y+0.9/0.5-y-5/2=0.3+0.2y/0.3求y
·0.4y+0.9/0.5-y-5/2=0.3+0.2y/0.3求y
y=(y')^3+y'
0.4y+0.9-0.3分之0.3+0.2y=1
0.4y+0.9/0.5-0.3+0.2y/0.3=1
0.4y+0.9/0.5-0.3-0.2y/0.03=1
0.4y+0.9/0.5 - 0.3-0.2y/0.3=1(0.4y+0.9)/0.5 - (0.3-0.2y)/0.3=1
0.4(y一0.2)十1.5二0.7y一0.38这道题如何解方程?
